Considerations on Loads Transmitted By the Bridge Inspection Installation on Support Structures

Abstract

The inspection of bridges is an essential activity to maintain the viability and safe operation of these structures. The inspection process shall be carried out by visual means using special equipment called bridge inspector. The equipment is similar in design to mobile crane installations – crane lorries, with the rotating part in the form of a boom at the end of which is the work platform for personnel and tools. The structure of the arm has the shape of a lattice girder or beams with closed section (caisson); regardless of the type of construction there is at least one telescopable section. During use, the installation is positioned on the superstructure of the bridges, supporting it by means of folding or telescopic outriggers.
